Question 11

What are the four types of tissues?

Answer 11

• connective tissue
• neural tissue
• epithelial tissue
• muscle tissue

Question 12

What does connective tissue do?

Answer 12

Binds cell and organs: protects
support and integration

Question 13

What does neural tissue do?

Answer 13

Excitable: allows propagation of
nerve impulses that communicate
between different parts of body

Question 14

What does epithelial tissue do?

Answer 14

Covers exterior, lines internal
cavities & some glands

Question 15

What does muscle tissue do?

Answer 15

Excitable, contracts: skeletal
(voluntary), smooth, cardiac

Question 16

What is there in place for tissue support?

Answer 16

• extracellular matrix
• cell junctions
• cell adhesion molecules

Question 17

What are the three types of junctions?

Answer 17

✿ gap junction (are communicating)
✿ tight junction ( are occluding)
✿ desmosome (cell-2-cell anchoring)

Question 18

What are some properties of connective tissues?

Answer 18

*protect, support & connect
- cells are dispersed in the matrix
- may be watery or mineralised

Question 19

What are some properties of epithelial tissues?

Answer 19

• protect/ regulate exchange
• one or more layers of cells
• their base is a thin layer of matrix ( basal lamina/ membrane)

Question 20

What are the functions of epithelial tissues?

Answer 20

• Exchange
• Simple, thin flattened cells,
  gaps/pores
• eg rapid gas exchange
• Blood vessels (also called
  endothelium) / lung
• Transporting

Question 21

What are the three types of epithelial tissues?

Answer 21

• squamous
• cuboidal
• columnar

Question 22

What is another specialised type of epithelial tissue?

Answer 22

• ciliated epithelial tissue
• sweeps fluid across surface

Question 23

What is homeostasis?

Answer 23

Physiologically, keeping the body’s
environment in a state of
equilibrium within “normal limits”

Question 24

What is positive feedback?

Answer 24

NOT HOMEOSTASIS
-“Positive feedback enhances or accelerates output created by an activated stimulus.
